Taking the Chinese A-share listed companies from 2010 to 2021 as the research sample, this article empirically tests the influence and mechanism of supply chain transparency on enterprise behaviour from the perspective of enterprise cleaner production. First, supply chain transparency has a significant governance effect on enterprise cleaner production. Second, compared with enterprises in high-concentration markets and eastern regions, this governance effect is more significant in low-concentration markets and central and western regions of China. Through the mechanism research, it is found that supply chain transparency can improve the level of enterprise cleaner production through the path of risk spill-over. Finally, the enterprises with weaker dialogue rights in supply chain information disclosure have a stronger governance effect, and this disclosure method has an alternative governance effect on enterprise green information disclosure. This study not only helps to enrich the research on the internal mechanism of enterprise cleaner production from the perspective of supply chain transparency but also guides the information disclosure system to promote enterprise cleaner production.
